concern:

CARL Boson, ALWIN citi- Empire, residing at Lud- Germany, have in- I-Iydrogenization and Dehydrogenization of Carbon Compounds,

is a specification.

of which the following Our invention relates to the hydmgenization and dehydrogenization 1n the presence of a catalytlc agent of compounds contaming carbon, means of which and dehydrogemzation can be carried and to catalytic mixtures,

the said hydrogenization out rapidly, wlth certainty, and at comparatemperatures.

-We have discovered that these advantages can be obtained by employing as the catalytic agent, an lntlmate mixture of nickel, cobalt, iron or.

metal, in particula a common copper, (hereinafter referred to. as the catalytic metal) with a compound containing fluorin. Complex compounds of fluorin are particularly advantageous for the purposes of this invention.

In order to produce the contact mass while employing fluorin, a solution of soluble compounds of the said compound can be employed for soaking the metallic com ound (for instance,

' which the catalytic or it is sufficient fluorin compound with, for

. nitrate. In those nickel carbonate) from metal is to be produced, merely to mix the said instance, nickel which insoluble cases in be employed,

prefer to precipitate the insoluble compound bv bringing together suitab e components in the. pound fromwhich be produced, for instance,

Both finely however, simple If of the-aforesaid kind, in ckel, cobalt and copper,

can be treated with fluorin compound chosen for the purpose of enhancing its catalytic activity. The catalytic mixtures according to this invention can be employed-for the hydrogenization and dehydrogenization of compounds of very varied nature. The catalytic reaction can be carried out either at ordinary pressure or under increased pres sure, for instance, above atmospheres.

The following example will serve to illustrate further the nature of this invention, which, however, is not confined to this ex.- ample. The parts are by weight:

Soak 100 parts of nickel carbonate in a concentrated solution of 10 parts of sodium silico-fluorid, then dry and treat with hydroen at 320 C. Introduce the contact mass thus obtained into the presence of air. and treat with hydrogen at a temperature of 120 C. and a pressure of 10 atmospheres. The reduction, and simultaneously the hardening, of the oil take place very rapidly. 1

Instead of sodium silico-fiuorid, other silico-fluorids can be employed, for instance those of aluminium, calcium, and potassium, or other fiuorin compounds, such, for instance, as barium fiuorid, calcium-boron fluorid, and potassium-titanium fluorid, can be used. Nickel wire netting can be similarly improved, for instance, by soaking it first withdilute nitric acid and then treating it with a solution of ammonium-silicofluorid, then adding a small quantity of aluminium nitrate and drying and reducing.
